It looks like one of the leads is shorting out when you have the monitor assembled. Check everything is islolated and not touching inside the monitor.

Having same problem where TV standby light comes on and logo appears momentarily then TV does not come on fully (backlight it on slightly).


Hello
You have to troubleshoot from its backlight inverter board itself. That is the first possible cause tho this fault to LCD TVs. If backlight inverter board have shorted inverter transormer [wnding short], the inverter board will take tremendous current from power supply, and this can lead to a momentory logo display and then shut down. The second possiblility is with its main digital board. In both cases, the respective board should be replaced as card basis, as there is no repair to these boards.

Turn itself off as soon as you turn it on (37MF33ID/37)


in the lcd tv there are three main parts
1)the inverter board(pannel)
2)the main board .
3)the power supply board.
----------
if there is no power at all them main board is faulty.if no front led light is coming ON there is no power .so the main board is faulty.on the main board there is a fuse located you have to replace that and check first if still no power main board needs to be checked and replaced
---------------
if there is sound but no picture and front led light is ON then its inverter board panel problem.if this is your case replace inverter panel.its located in the lower side of the lcd in the inner area below the main board.
-----------
but if there is just front led light blinking , but no picture or sound then its power supply board problem.
------
but as you mentioned that the tv turns ON for some seconds then automatically turns off this indicates that the power supply board is not faulty but there is a component on the board that is getting over heated because its got weak so due this overheating of a component the circuit gets short and tv shuts off.
on power supply board there are some capacitors and ic located.if any of the component gets short or budged up then it short the power supply board.so you can check the components on power supply board with multimeter and get it replaced by using soldering iron.
----------
also you can get new replaCEment power supply board.this clears the problem completely.
---------
you can get the required board and components at ----- www.partstore.com -------- or from ------ www.radioshack.com ----
---------
if you are not familiar with doing this you can get it done by local tv repair technician familiar with this model tv.
-----------
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

The screen was black when turned on but could make out what was on the screen when facing the light


You have 1 of 2 issues...

1.) You have a Bad LCD Bulb.. You can get a replacement LCD Bulb and change the LCD Bulb inside the Display which is cheaper and easier than replacing the whole backlight panel.... LCD bulbs cost around $12 Be careful these bulbs are Fragile and if bent when installing- will break...

2.) You have a failing Power Inverter... this is located just under the screen display panel,, it is a circuit board that the screens lcd bulb plugs into and the display cable plugs into... this inverter board converts the DC power in the laptop back to AC power because the screen needs more power to power the lcd bulb...

Your Problem Is One of These 2 Things... Your Best Bet Is To Test The Power Inverter First - Since It Is The Easier Of The 2 To Replace/Repair
